Solidago odora.

Botanical name: 

The leaves of the sweet Golden Rod are mildly excitant an agreeably aromatic. They are occasionally used in flatulency, colic, etc., as a carminative. The infusion constitutes a very pleasant diaphoretic and diluent. It imparts an agreeable flavor and odor to less acceptable medicines, and corrects their nauseating and irritating qualities. The infusion may be taken freely.

The American Eclectic Materia Medica and Therapeutics, 1898, was written by John M. Scudder, M.D.
